; it may be chronic or acute.
backflow of blood from the left ventricle into the left atrium, owing to insufficiency of the mitral valve
; it may be acute or chronic, and is usually due to mitral valve prolapse, rheumatic heart disease, or a complication of cardiac dilatation.
backflow of blood from the pulmonary artery into the right ventricle, owing to insufficiency of the pulmonic valve

mitral regurgitation Chronic mitral valve regurgitation, mitral insufficiency Cardiology Backflow of blood from the left ventricle to the left atrium due to a defective mitral valve, which ↓ forward flow of blood and ↑ work by heart to pump more blood to compensate for inefficiency; acute MR may be due to valve dysfunction or injury post MI or infectious endocarditis, which may cause rupture of the valve, papillary muscle, or chordae tendineae–which anchor the valve cusps, resulting in valve leaflet prolapse into the atrium, leaving an opening for the backflow of blood; chronic MR is prolonged and progressive, and often associated with mitral valve prolapse, characterized by weakening and ballooning Etiology Rheumatic heart disease–thickening, rigidity, retraction of mitral valve leaflets; ASHD, HTN, left ventricular enlargement, connective tissue disorders–eg, Marfan syndrome, congenital defects, endocarditis, heart tumors, late syphilis, untreated acute MR.

Patient discussion about mitral regurgitation
Q. what do you do with a broken heart? I HAD A ECHO DONE THIS WEEK AND CONCLUSION WAS: 1)SEVERE MIRTAL REGURGITATION WITH LEFT ATRIAL DILATATION 2)LOW NORMAL LV FUNCTION CHEST X RAY IMPRESSION WAS: 1)NORMAL SIZE HEART WITH PROMINENT LEFT HEART BORDER. 2)PROMINENT MARKINGS WITH PROMINENT CHANGES. 3)THE BONES ARE OSTEOPENIC. BLOOD TEST....CHEMISTRY B TYPE NATRIURETIC PEPTIDE HIGH 260
A. The left atrial dilatation is likely the cause of the elevated beta natriuretic peptide. A cardiologist should be able to talk with you about dealing with the mitral valve regurgitation.More discussions about mitral regurgitation
